Abstract
When the secondaries of current transformers (CTs) are connected in parallel to a spill circuit with nonzero impedance, then the CT simulations are coupled by the common voltage across this spill circuit. This paper considers the case of two CTs feeding a high impedance spill circuit and gives a comparison of simulation and test results
